Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of garbage cans, and particularly relates to a preassembled garbage can capable of being transported in a nested manner. BACKGROUND

[0002] When garbage can products with lids are transported in bulk, transporting them in the form of complete assembled products can result in excessively large transportation volumes and thus excessively high transportation costs. At present, they are mostly transported in the manner of "a plurality of can bodies being nested, and a plurality of lids being placed in the can body at the top end". The split can bodies and lids are transported to the destination in the form of semi-finished products and then assembled again. Since the need for secondary assembly exists, the higher the preassembly completeness of the garbage can is, the more convenient the subsequent assembly by the user is, which is conducive to improving user experience and saving costs of guided installation, after-sales communication, etc.

[0003] At the same time, one of the main markets of the applicant's products is the European and American regions. Through investigation and feedback from downstream distributors, it is found that, due to high labor costs, the staff of large stores (such as Wal-Mart, Costco, etc.) in foreign countries will not assemble the semi-finished components transported in bulk, but will directly stack and sell them. Since a plurality of lids are placed in the can body at the top end, it is easy for the store staff to miss the lids when packing for customers or for customers to take the lids by themselves, resulting in store losses or the need for additional after-sales operations by the user.

[0004] In summary, it is particularly necessary to design a garbage can that can be sold in the form of "one can and one lid" and does not hinder the nesting of multiple can bodies, and has high preassembly completeness. In order to achieve the above-mentioned needs, the applicant designs a fixing structure for disassembling and assembling the lid, i.e., the utility model patent with the application number 2022234846672. The product includes a decorative ring and a lid that are separately arranged with a can body of a garbage can. The can mouth of the can body is preassembled with the decorative ring and at least one rotatable connecting piece. The arrangement of the decorative ring and the connecting piece of the lid does not hinder the stacking of multiple can bodies, and the transportation volume is as small as possible, which is conducive to controlling the transportation cost. One connecting piece is provided as a lid connecting piece, and a matching engagement structure is provided between the lid connecting piece and the lid. A matching hanging structure is provided between one side of the can body and the lid. The lid is hung on one side of the can body before installation and does not hinder the nesting of multiple can bodies, and can be placed and sold in the form of "one can and one lid".

[0005] However, the inventor found that the product still has room for improvement during the product iteration process:

[0006] I. The bucket cover of the above-mentioned patent requires the manufacturer to design an additional and non-standard assembly step during assembly, i.e. manually or mechanically attaching the bucket cover to one side of the barrel body, so the inventor believes that the product still has room for improvement in assembly, and the bucket cover of the product can be completely separated from the barrel body, which still has the risk of being lost.

[0007] II. The bucket cover of the above-mentioned patent is a completely independent part, and the user needs to insert the bucket cover with the connecting piece after receiving it. Although a relatively simple and intuitive structure design has been achieved, some users may not align the direction when inserting and may forcefully insert, resulting in deformation or breakage of the parts. Home product design is a process of continuously making more detailed and humanized designs for users, so the inventor believes that there is room for improvement in the installation structure and installation method for users. SUMMARY

[0008] In view of the problems in the related art, the utility model provides a preassembled garbage can capable of being transported in a nested manner to overcome the above-mentioned technical problems existing in the prior art.

[0009] The technical scheme of the utility model is as follows:

[0010] A preassembled garbage can capable of being transported in a nested manner, comprising a barrel body and a bucket cover matched with the barrel opening of the barrel body, wherein the barrel body is preassembled with a moving part for guiding, driving or limiting the movement of the bucket cover, the outer contour of the barrel body preassembled with the moving part and the internal space of the barrel body are both wide at the top and narrow at the bottom, and a plurality of barrel bodies preassembled with the moving part can be nested with each other.

[0015] Compared with the prior art, first, the bucket cover of the utility model can be turned on one side of the bucket body and kept in rotational connection with the bucket body before fastening, realizing the matching selling form of "one bucket one cover", avoiding the problems of wrong taking, missing, and losing the bucket cover, and the like, and at the same time, to realize the firm rotational connection between the bucket cover and the bucket body, the installation difficulty is also relatively large in general, and the utility model also pre-assembles the parts arranged in rotational connection by the production factory with higher professional degree;

[0016] Secondly, since the installation difficulty between the moving part and the bucket body is also relatively large in general, the utility model designs the fastening joint which is small in size and does not hinder the stacking of the bucket body, and the fastening joint can replace the pre-connection of the bucket cover with the moving part, so that the moving part with large installation difficulty can also be pre-assembled by the production factory;

[0017] Finally, the coaxial design of the utility model makes the bucket cover and the fastening joint have only one activity track, that is, only coaxial rotation, and in combination with the fastening design of the resilient clamping block and the clamping hole, the user only needs to turn the bucket cover hinged to the bucket body to contact the fastening joint, and then slightly exerts force to make the two close, and the locking action is performed by the resilient clamping block using elasticity, without manual locking by the user, the pre-assembly completeness of the utility model is high and the fast assembly can be conveniently carried out, the user experience is improved, and the extremely convenient installation also reduces the probability of damaging parts in the installation process of the user.
